Abstract Several endemic species of Sulawesi have different growths and are generally influenced by local environmental factors. There are three well-known endemic species of Sulawesi, namely Macadamia (Macadamia hildebrandii), Elmerillia (Elmerillia ovalis), and Gophasa (Vitex cofassus). These three species are widely developed in community forests and are the mainstay of the community as building materials and for other purposes. These three species can be used as good absorbers of carbon dioxide from the atmosphere in the context of mitigating climate change. Macadamia and Elmerillia species grow well in the highlands, while Gophasa is generally found in the lowlands. From the results of the growth analysis, it is known that Macadamia and Elmerillia are medium growing species, while gophasa are slow-growing species. The results showed that the three endemic species have a good ability to absorb carbon from the air. At the age of 20 years, these three species can store carbon which is quite high, namely 132.38 tons/ha for Macadamia, 152.04 tons/ha for Elmerillia, and 82.65 tons/ha for gophasa. When converted to the ability to absorb CO2 from the atmosphere, the three species can absorb 485.85 tons CO2/ha, 557.99 tons CO2/ha, and 303.33 tons CO2/ha, respectively.

Negative Influence

Anthropogenic impacts, such as deforestation, soil erosion, and carbon dioxide emissions, have a negative influence over global warming due to the increase of CO2 levels in the atmosphere. The sustainable forest management is a way to mitigate climate change owing to the carbon storage capacity of forests. This study highlights the priority of forest management according to the integrated assessment of carbon storage under anthropogenic impacts in the administrative units of Ecuador. In the obtained map, the provinces Guayas, Esmeraldas, and Manabí showed the highest values of 25, 22.85 and 19.9, respectively, followed by two Amazon provinces, Morona Santiago and Sucumbíos. Therefore, we concluded that deforestation, soil erosion, and carbon dioxide emissions were more pronounced on the coast mainly due to agriculture and livestock activities and the forests in these provinces must have priority management. This analysis is useful for planning environmental practices in order to increase carbon storage as a strategy of mitigation for global warming.

Abstract. The spatial distribution of the air-sea flux of carbon dioxide is a poor indicator of the underlying ocean circulation and of ocean carbon storage. The weak dependence on circulation arises because mixing-driven changes in solubility-driven and biologically-driven air-sea fluxes largely cancel out. This cancellation occurs because mixing driven increases in the poleward residual mean circulation result in more transport of both remineralized nutrients and heat from low to high latitudes. By contrast, increasing vertical mixing decreases the storage associated with both the biological and solubility pumps, as it decreases remineralized carbon storage in the deep ocean and warms the ocean as a whole.
